Description of the Invention: [Technical Field] The present invention relates to a stylus, and more particularly to a stylus applied to a touch screen. [0002] 先前 [Prior Art] In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices in which a translucent touch panel is mounted in front of a display device such as a liquid crystal are gradually formed. increase. The user of such an electronic device visually confirms the display content of the display device located on the back surface of the touch panel by the touch panel, and presses the touch panel to operate by a finger or a pen. Thereby, various functions of the electronic device can be operated. [0003] According to the working principle of the touch screen and the transmission medium, the previous touch screens are divided into four types, namely, resistive, capacitive, infrared, and surface acoustic waves. Among them, the capacitive touch screen is widely used due to its high sensitivity and small touch force. 0004 [0004] The previous capacitive touch screen includes a transparent conductive layer connected with a plurality of electrodes. In use, a finger or a stylus is usually used to touch the surface of the capacitive screen, and a touch object and a transparent conductive layer are formed. A contact capacitor senses an electrical signal between the touch point and each electrode of the transparent conductive layer on the surface of the touch screen through an external circuit, so that the position of the touch point on the touch screen can be determined. In order to obtain good conductivity, the tip of the previous stylus is generally made of metal. However, the tip of the stylus made of metal has a high hardness, which is liable to damage the touch screen, and the contact capacitance and sensitivity when it comes into contact with the touch screen. 099146743 Form No. A0101 Page 3 of 56 Page 9292080311-0 201227428 Still needs improvement. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a stylus having a large contact capacitance with a touch screen during use, having high sensitivity, and having less damage to the touch screen. A stylus pen includes a pen holder and a pen tip, the pen tip being flexible and electrically conductive. The tip of the pen forms a contact capacitance with the touch screen when in use. The pen tip is a bundle structure composed of a plurality of nano carbon pipes in parallel. [0007] A stylus pen includes a pen holder and a pen tip, the pen tip having flexibility and electrical conductivity, and the pen tip forming a contact capacitance with the touch screen when in use. The writing head is a bundle structure composed of a plurality of carbon nanotube composite wires. [0008] Compared with the prior art, since the carbon nanotube has very good electrical conductivity, large specific surface area, and good flexibility, the contact area of the stylus pen of the present invention is in contact with the capacitive touch screen. The contact capacitance on the upper part is large and has high sensitivity. In addition, since the carbon nanotube has a smaller coefficient of friction than metal, the tip is less likely to damage the touch screen. [Embodiment] The touch screen stylus of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Referring to FIG. 1, a first embodiment of the present invention provides a touch control pen 100 for a touch screen. The stylus 100 includes a pen holder 110 and a pen tip 120 disposed at the end of the pen holder 110. The tip 120 has flexibility and electrical conductivity. [0011] The function of the pen 110 of the stylus pen 100 of the present invention is mainly to provide a user with a gripping position when the pen tip 120 is operated. When the stylus 100 is a pen that is touch-operated by the body of the human body 099146743, the form number A0101, the fourth page, or the 56 page of the 0992080311-0 201227428, the pen holder 1 1 0 needs to have a hand on the hand. The static charge is transmitted to the function of the pen tip 12G, that is, the pen holder 11〇* is to be electrically connected to the pen tip 12G. When the touch is not a pen that achieves a touch operation by the human body, as in the signature 110, a capacitive conductor electrically connected to the pen head 120 is [[8] 12] ❹ [0013] The capacitor is not necessarily-conductively connected between the pen 11G and the pen tip 12G, and only the contact capacitance can be formed between the pen tip 12G and the touch screen. It can be understood that the material, structure, and shape of the pen 11 of the stylus pen 100 of the present invention and the connection mode (10) with the pen ray 0 are selected or changed according to actual needs. In the present embodiment, the human body static electricity control pen (10) is read and the cylindrical metal pen holder 110 is taken as an example to focus on the structure of the pen head 120 of the stylus pen (10) of the present invention. Referring to Fig. 2, the pen holder 11() has a hollow cylindrical knot #1 having a fixed end 114. The fixed end 114 of the pen holder 11G is internally provided with an internal thread for mounting the pen tip 12, and the pen tip 12 is screwed into the fixed end 114 of the pen holder. When the pen tip 120 falls into the fixed end 114 of the pen holder 11 ,, the pen tip 120 is electrically connected to the pen tip 110. It can be understood that the manner in which the pen tip 12 〇 is connected to the pen holder 110 is not limited to this 'the appropriate manner can be selected according to the shape, structure and material of the pen holder 11 〇 and the pen tip 120 in various connection manners in the prior art' as long as the pen holder 11 can be secured ( ) It can be connected with the 12-inch pen. Referring to Fig. 3, the pen tip 120 is composed of a support body κι and a touch material layer 125. The touch material layer 125 is disposed on an outer surface of the branch body 121. The support body 121 is made of a flexible material, and the contact material layer 125 is made of a flexible conductive material.

Since the pen tip 12 is flexible, in use, the contact area between the pen tip 12 and the touch screen can be controlled by pressure, thereby controlling the contact capacitance between the stylus pen 1 and the touch screen. [0015] The support body 121 has a fixing portion 122 and a main body 124. The fixing portion 122 and the main body 124 may be integrally formed with an integral solid structure. The outer surface of the solid portion 122 is provided. The external thread is aligned with the internal thread of the fixed end 114 of the sheath 110 so that the tip 12〇 can be fixed to the fixed end 丨4 of the sheath 11 。. The shape of the main body 124 can be designed according to actual needs, and can be spherical, tapered, rounded, or the like. The body 124 is used to set the touch material layer 125, and the touch material layer 125 may cover the whole body 124 or may partially cover it. The layer of touch material 125 at least partially covers the junction of the fixing portion 122 and the body 124 such that the touch material layer 125 is electrically connected to the sheath 110 after the tip 120 is mounted on the fixed end 114 of the sheath 11A. The support body 121 is composed of a flexible south sub-material: the flexible polymer material may be tantalum rubber, polyurethane, polyethyl acrylate, polybutyl acrylate, polystyrene, polybutadiene, and polypropylene. A combination of one or more of nitriles and the like. The support body 121 may also be composed of a flexible polymer material having a relatively high dielectric constant, and the high dielectric constant flexible polymer material may be in a colloidal state. The support body 121 may also be a conductive polymer material. The conductive polymer material has a high dielectric constant, and when used as the support body 121, the pen head 120 itself has a large capacitance. The conductive polymer material may be polyaniline, polypyrrole or polythiophene. In this embodiment, the 099146743 form number A0101 page 6 / 56 page 0992080311-0 201227428 The material of the support body 121 is ruthenium rubber. [0016] Referring to FIG. 4, the support body 121 may also be a support structure 121 of a hollow structure. A closed space 126 may be formed in the interior of the body 124 to form a hollow structure of the tip 120. 1毫米至2毫米。 When the support body 121 is a hollow structure, the wall thickness can be selected from 0.1 mm to 2 mm. When the support body 121 has a hollow structure, the flexibility of the pen tip 120 can be further improved. Referring to FIG. 5, the touch material layer 125 may be formed in an spiral strip shape on the outer surface of the body 124. The spiral radius of the spiral strip-shaped touch material layer 125 gradually increases in the direction of the pen tip 110 toward the sheath 110. Specifically, the outer surface of the main body 124 may be provided with a spiral groove whose spiral radius extends spirally from the end of the main body 124 toward the fixing portion 122, and the spiral radius is small to large. The touch material layer 125 may be disposed within the spiral groove and the thickness of the touch material layer 125 is greater than the groove depth such that the touch material layer 125 protrudes from the outer surface of the body 124 for Contact with the touch screen. The spiral radius of the spiral strip-shaped contact material layer 125 is gradually increased from the tip of the pen tip 120 toward the sheath. In use, as the pressure increases, the degree of bending of the tip 120 increases, and the area in which the touch material layer 125 contacts the touch screen substrate also gradually increases. Thereby, the size of the contact area with the touch screen can be controlled, thereby controlling the thickness of the stroke. Since the spiral strip-shaped touch material layer 125 only partially covers the surface of the main body 124, the raw material is saved compared to completely covering the surface of the main body 124. It can be understood that the surface of the main body 124 may not be provided with a spiral groove, and the spiral strip-shaped touch material layer 125 is directly disposed on the surface of the main body 124, and the end portion of the main body is fixed to the fixed portion 099146743. Page 7/56 pages 0992080311-0 201227428 122 The spiral extends and the radius of the spiral varies from small to large along the tip of the pen toward the sheath 110. [0018] The touch material layer 125 is for contacting the surface of the touch screen and forming a contact capacitance therewith. The change in contact capacitance is achieved by a change in the contact area with the touch screen, so that the touch screen can sense the thickness of the stroke. The touch material layer 125 may have a thickness of from 1 micrometer to 2 millimeters, and the touch material layer 125 is electrically conductive. In order to increase the specific surface area of the touch material layer 125, the touch material layer 125 may be: a carbon nanotube, a graphene; a composite material composed of a carbon nanotube and a flexible polymer; and a graphene and a flexible polymer. Composite material; or a composite of carbon nanotubes and metal. The following will introduce the composite material formed by uniformly dispersing the carbon nanotubes in the flexible polymer matrix, and the carbon nanotube structure is arranged on the surface of the flexible polymer matrix to form a composite material, and each nanotube in the carbon nanotube structure The surface of the carbon nanotube is coated with a conductive layer, and the graphene is uniformly dispersed in the flexible polymer matrix or a composite material formed on the surface of the flexible polymer matrix. Referring to FIG. 6, the touch material layer 125 may be composed of a carbon nanotube high molecular composite material. The carbon nanotube polymer composite is composed of a flexible polymer matrix 24 and a plurality of carbon nanotubes 22 dispersed in the flexible polymer matrix 24. The plurality of carbon nanotubes 22 are uniformly dispersed in the flexible rfj molecular matrix 24 and interconnected to form a conductive network. In order to achieve the formation of a conductive network in the flexible polymer matrix 24 of the carbon nanotubes 22, the mass percentage of the carbon nanotubes 22 should be greater than 5%. Since the carbon nanotube 22 has a very large specific surface area and high conductivity. When the pen tip 120 is in use, since the touch material layer 125 has a large specific surface area 099146743, the form number A0101, page 8 / total 56 page 0992080311-0 201227428 wide α, stores more from the user's hand. The static charge increases the contact capacitance between the 7 I and the 12-inch touch screen. In addition, the layered touch material composed of the polymer composite material of the "T-meter carbon sound 22" and the capacitance per unit area formed by the touch panel are larger, and it is more flexible: and because the carbon nanotube 22 is a hollow structure, It has a very small = mass I, and its special chemical bond structure allows the carbon nanotube 22 to have the strength and modulus of elasticity of the non-Wei». In addition, due to the very large length ratio of the carbon nanotube 22 (greater than i: 1:), the carbon nanotube 22 has a very good (10) property, and the shape can be recovered after applying an external force. S, the tip 12 of the polymer composite material formed by the carbon nanotube 22 and the soft polymer matrix 24 has a lighter quality and a higher scratch resistance, thereby having a longer service life. . A pen tip 120 composed of a polymer composite material composed of a dispersed carbon nanotube 22 disposed in the flexible polymer matrix 24 may have a portion of the carbon nanotube 22 outcrops from the outer surface of the polymer matrix 24, thereby being better. Contact with the touch screen, and because the carbon nanotube composite is softer than metal, it is not susceptible to damage to the touch screen. [0020] The flexible polymer matrix 24 is a sheet having a thickness of between 2 micrometers and 2 millimeters. The flexible polymer matrix 24 is composed of a flexible polymer material, and the flexible material is not electrically conductive. Limit, as long as it is flexible. The material of the flexible polymer matrix 24 is a flexible polymer material, such as one of ruthenium rubber, polyurethane, polyethyl acrylate, polybutyl acrylate, polystyrene, polybutadiene, and polyacrylonitrile. Combination of several types In the embodiment, the material of the flexible polymer matrix 24 is ruthenium rubber.

The surface of the flexible polymer matrix 24 is formed. Referring to FIG. 8, the carbon nanotube structure 12 having a unitary structure may be disposed adjacent to the surface of the flexible polymer matrix 24 disposed in the flexible polymer matrix 24. The surface of the carbon nanotube structure 12 disposed adjacent to the flexible polymer matrix 24 is disposed in the flexible polymer matrix 24, meaning that the carbon nanotube structure 12 is completely or partially embedded in the thickness direction thereof. In the polymer matrix 24, and when the carbon nanotube structure 12 is completely embedded in the flexible polymer matrix 24, the distance from the surface of the carbon nanotube structure 12 to one surface of the flexible polymer matrix 24 is 10 μm or less. 'Thereby ensuring that the touch/material layer 12 is electrically conductive. [0022] The carbon nanotube structure 12 is a self-supporting structure. The so-called "self-supporting structure" means that the carbon nanotube structure does not need to be supported by a support body, and can maintain its own specific shape. The self-supporting structure of the carbon nanotube structure 12 includes a plurality of carbon nanotubes 22 which are mutually attracted by the van der Waals force so that the carbon nanotube structure 12 has a specific shape. Since the carbon nanotube structure 12 is self-supporting, a layered or linear structure can be maintained without being supported by the support. The carbon nanotube structure 12 has a large amount of gaps between the carbon nanotubes 22, so that the carbon nanotube structure 12 has a large number of pores, and the flexible polymer matrix 24 penetrates into the pores, and the nanocarbon The tube structure 12 is tightly coupled. [0023] In the carbon nanotube polymer composite, the flexible polymer matrix 24 is filled in pores in the carbon nanotube structure 12. The flexible polymer matrix 24 is intimately bonded to the carbon nanotubes 22 in the carbon nanotube structure 12. The flexible polymeric matrix 24 encases the entire carbon nanotube structure 12. The carbon nanotube structure 12 maintains a layered structure in the flexible polymer matrix 24. Flexible Polymer 099146743 Form No. A0101 Page 10 of 56 0992080311-0 201227428 [0024] 00

In addition, due to the gap between adjacent carbon nanotubes in the nanocarbon pipeline, the nanocarbon pipeline has a large number of pores. The pore size is less than about 1 〇 micrometer. Referring to Fig. 19, in the present embodiment, the touch material layer j25 is also composed of a porous nano tube-breaking composite material formed of the above-mentioned carbon nanotube structure 12 and a conductive material. The carbon carbon structure 12 in the porous carbon nanotube composite material maintains its structure, and the surface of each of the carbon nanotube tubes 22 in the carbon nanotube structure 12 is coated with a conductive material layer 226. There is a gap between the nano-tubes 2 2 of the porous 'T' carbon nanotube composite material coated with the conductive material layer 2 2 6 , and therefore, the porous nano-tube tube gas house material has a plurality of micro-packages Hole 225. The pores 225 have a pore diameter of 5 μm or less. The conductive material layer 226 may be a conductive polymer layer, and the conductive polymer layer may be one or more of polyaniline, polypyrrole, polythiophene, polyacetylene, polyparaphenylene, and polyparaphenylene ethylene. The thickness of the conductive polymer layer is preferably between 30 nm and 150 nm. In the present embodiment, the thickness of the conductive polymer layer is from 50 nm to 90 nm. The conductive polymer layer preferably has a mass percentage of 20% to 80% in the composite film composed of the carbon nanotube and the conductive polymer material. In this embodiment, the conductive polymer layer is a polyaniline layer, and the conductive polymer layer is coated on the surface of the disordered carbon nanotube network structure. The polystyrene has a relatively high dielectric constant, so the porous carbon nanotube composite also has a high dielectric constant, so that the tip 120 composed of the porous carbon nanotube composite material has a better contact with the touch screen. Large capacitance. The material of the conductive material layer 226 may also be an elemental metal or a metal alloy, and the elemental metal may be copper, silver or gold. The form of the conductive material layer 226 is compiled from 0 to 10 pages. Page 92 0992080311-0 [0037] 201227428 The thickness is 1 ~ 20 nm. In the present embodiment, the material of the conductive material layer 2 26 is silver and has a thickness of about 5 nm. Alternatively, a wetting layer may be further included between the carbon nanotube 22 and the conductive material layer 226. The wetting layer functions to better bond the layer of conductive material 226 to the carbon nanotubes 22. The material of the wetting layer may be a metal such as nickel, palladium or titanium which is wettable with the carbon nanotube 22 or an alloy thereof, and the wetting layer has a thickness of 1 to 10 nm. Alternatively, in order to better bond the wetting layer and the conductive material layer 226, a transition layer may be further included between the wetting layer and the conductive material layer. The material of the transition layer may be a material which can be well combined with the material of the wetting layer and the material of the conductive layer, and the thickness of the transition layer is 1 to 10 nm. [0040] In the carbon nanotube composite layer, after the carbon nanotube structure 12 is combined with the conductive material, the porous carbon nanotube composite material has better electrical conductivity and transmits charge at the time of contact with the touch screen. Faster, therefore, the reaction speed of the touch screen stylus 10 can be increased. Since the porous carbon nanotube composite layer includes a plurality of micropores 225, the porous carbon nanotube composite material has a large specific surface area, so that the electrostatic charge transmitted by the user's hand can be stored more, thereby When the touch screen is in contact, a large contact capacitance can be generated, so that the sensitivity of the touch screen can be improved. [0041] It can be understood that the touch material layer 152 of the pen tip 120 of the first embodiment of the present invention may also be composed of a pure carbon nanotube. The touch material layer 125 on the surface of the tip 120 may be formed by wrapping the above-described carbon nanotube structure 12 on the surface of the body 124. Specifically, the carbon nanotube structure 12 may be wound around the outer surface of the body 124 and bonded to the body 124 by an adhesive at 099146743 Form No. 1010101 Page 18/56 Page 0992080311-0 201227428 The rice bran structure 1 2 at least partially covers the fixing portion 1 22 j and is electrically connected to the pen # 11Q. Since the nano-carbon nanotube structure U has a large specific surface area, the carbon nanotube structure has a higher ratio than the above table. When the carbon nanotube structure 12 is in contact with the Na-screen, °' Producing a large contact capacitance makes the stylus 1 〇 have higher sensitivity. In addition, the carbon nanotubes are smoother and have a smaller coefficient of friction, which does not cause damage to the touch screen. [0042] 触 Ο μ Referring to FIG. 20' The touch material layer 125 may also be composed of a graphite thin-layered "material" formed by dispersing graphite: 28 in the material of the flexible polymer matrix 24. The stone lion 28 is uniformly dispersed in the flexible high molecular soil 24. In the graphene polymer composite material, the flexible graphite matrix may also be readable, thereby exposing the surface of the touch material layer 125. The volume percentage of the graphite thinner 28 in the flexible 1±two-blade base 24 is 丨(10)^ to 6〇%. Referring to Fig. 21', the graphite thin 28 series is a lamellar structure composed of a plurality of six-membered ring carbon atoms. The thickness of the graphene 28 is 100 nm or less, and the thickness of the graphene 28 in the present embodiment is 0.5 nm to 1 nm. Graphene 28 has good electrical conductivity and it delivers electrons very rapidly at room temperature. Graphene 28 also has a large specific surface area and is flexible. Therefore, the graphene polymer composite material composed of the graphene 28 and the flexible polymer matrix 24 also has a large specific surface area and conductivity. Therefore, the tip 120 formed of the above material is also compared with the capacitance per unit area formed by the touch panel. Large, and has good conductivity, the tip 12 〇 has higher sensitivity. [0043] In the present embodiment, the raw material of the graphene 28 is prepared by a chemical dispersion method. 099146743 Form No. 1010101 Page 19 of 56 0992080311-0 201227428 Chemical Dispersion Method Mix the graphite oxide with water in a ratio of 1 mg : 1 mL, shake it with ultrasonic waves until the solution is clear and free of particulate matter, and add an appropriate amount of 肼 at 100 After refluxing for 24 h at ° C, a black granular precipitate was produced, and the graphene powder was obtained by filtration and drying. The pen tip 120 composed of the graphene polymer composite material composed of the dispersed graphene 28 disposed in the flexible polymer matrix 24 may have a portion of the graphene 28 outcrops from the outer surface of the pen tip to better contact the touch screen. Moreover, the graphene 28 is relatively smooth and has a small friction coefficient, and does not cause damage to the screen of the touch screen during use. Referring to FIG. 22, the touch material layer 125 in the first embodiment of the present invention may be formed by covering the surface of the flexible polymer substrate 24 with the graphene layer 28 to form a graphene layer 280. The graphene layer 280 has a thickness of from 100 nanometers to 1 micrometer. The graphenes 28 in the graphene layer 280 may be arranged in an overlapping manner, juxtaposed, or overlapped with each other. Graphene has good electrical conductivity and it delivers electrons very quickly at room temperature. The graphene layer 280 has a thickness of a single layer of graphene to a thickness of 1 mm. In this embodiment, a graphene material is prepared by a chemical dispersion method. The chemical dispersion method mixes graphite oxide and water in a ratio of 1 mg: 1 mL, and oscillates with ultrasonic waves until the solution is clear and free of particulate matter. After adding an appropriate amount of hydrazine at 100 ° C for 24 hours, a black granular precipitate is produced, which is filtered and dried. Graphene powder. After the graphene 28 is obtained, the flexible polymer matrix 24 is placed in the graphene powder. Since the graphene 28 is a nano material, it has a certain adhesion and can adhere to the surface of the flexible polymer matrix 24 to form. Graphene layer 280. It can be understood that the graphite thinner 28 can also be fixed to the surface of the flexible polymer matrix 24 by a binder to form the graphene layer 280. [0045] It can be understood that the touch material layer 125 can also be covered by the graphene 28 straight 099146743 form number A0101 page 20 / 56 page 0992080311-0 201227428 to cover the graphite thin material formed on the surface of the body 124 Layer composition. The layer of the graphene material has a thickness of from 100 nm to 1 μm. The graphene in the graphene layer may be arranged in an overlapping manner, juxtaposed, or overlapped with each other. Graphene has good electrical conductivity and it delivers electrons very quickly at room temperature. The thickness of the graphene is from 0.5 nm to 100 nm. Referring to FIG. 23, a second embodiment of the present invention provides a stylus 200 that includes a pen holder 110 and a pen tip 220. The main difference between the embodiment and the stylus 100 of the first embodiment is that the stylus pen 220 is a solid core structure composed of the same material. The material of the tip 22〇 may be selected from any material other than pure graphene in the material constituting the touch material layer 125 in the first embodiment, and the specific material of the touch material layer 125 may be referred to the first embodiment.
